Various other objects and "advantages will :be

apparent nom the *following description 'of 'two embodiments of theinvention, and the "novel features will be partioulalry pointedout/hereinafter in connection with the appended claims.

In the accompanying drawings: Fig. 1 is a transverse, sectionalelevation through a device constructed in acoord'ance with theinvention,and with the parts in the positions occupied when 'the device l is usedas: a sofa seat, the section being taken along the 1 inside f-ace of oneof the end members of the support andlooking toward the other endmember;

"Fig. 2 is'-a"'similar sectional elevation, but with the pa'rts'sho'wnin the "positions'oocupied when the device isusedas a bed;

"Fig. 3 is aplan or the same, with the'partsin "gs-4 is a "sectionalelevation somewhat similar to Fig. 1, but illustrating a sli'g ht 1modification thereof; and

Fig. '5 isia sectiona -elevation somewhat similar to Fig. 2, but withthe-parts constructed as shown Fig. '4.

In the embodiment of the invention illustrated 'in'FigsJl to "3-; theimproved' sofa bed includes a t'supportvformedof upstandingpparallel'endmemhers I "and 12 spacedapart inffaceto, face relation and connected "by"an "intermediate rigid portion formed "by "crossmenibers '3, I, 5"and'6. "Amattressesupporting frame shown as a shallow box withinanopen'face is disposed between the end members I and 2, and is formed ofa front section 6 and-a rear section I that are hinged together at theends of their abutting edges by hinge 'pins 8. One of the frame sectionscarries a follower or "roller preferably one ateach end, whichis guidedby a cam carried by the adjacent end member, so as to control and guidethe-frame sections as they move in each direction between sofa bed andsofa seat positions. In this illustrated embodiment of the invention,the rollers or followers 9 areattached tot-the frame sections at their.hinged connection. For this purpose these pins .8 extend endwise fromthe sections 6 and I and carry rollers!) that serve as cam followers andrun in arcuate, upstanding grooves I0 provided in the inside faces ofthe end members 1 and'2. Each camgroove til at its upper end is bentiforwardly and downwardly at l l.

The front section 16 is provided witha bottom wall 12, and withend walls53 and M which extend iniboth directions beyond the bottom wall A 2 totheoppositezfaces thereof. o'fthe end walls .l3iand M 'areJhinged bypins-or The extensions pivots 15 upon'the upper BIldSiOf links lit-whichat their outen'endsJare pivoted onbearing studs ll carried by the :endmembers. I and '2. pins or pivots =15 :are located intermediate the Thetreat and rear edges of'the end walls [3 and 1M,

and the links '56 are upwardly .andrearwardly inclined when the frontsection Blisupstanding in sofa-seat position, as showninFig. 1. The,rear section 1 is similar to frontsectionfi, inithat it has a bottomwall [8 and end walls [9 and 28 which extend in both 4 directions from100th :faces of the bottom [8, as shown in Fig. 1. .Eachend wall 19 and'210 is pivoted intermediate ofitsifront and rear edges byrpivots orpins2l upon the upper ends of linlts '22, and the. lower. endsofthoselinks "are pivoted onstuds-23 carried'onitheiinnenfaces 'of the endWaHsW-and2. l

"When :the device is in sofacseat l position shown inFig. l, the openfaces 'o'f thexltwo :sectionsfi and '1 abut f'acato face with .thechamberscof the sections combined; When the sectionwfi pulled forwardly,it will rock on the pivotipins 'l5,and the links-l6 Will at thesame-time swing forwardly to allow the sections fi and to- "open like abook, the sections moving forwardly toward a horizontal-position and'the SGtiOh'i] moving *rearwardly toward a horizontal position.

"The" links 22=allow the rear seotion 'l to moverearwar'dly for thispurpose; and; du'ring 'this 'opefiing movement the rollers- 9 onmeninges 8 that c'on 3 nect the sections 6 and I move upwardly along thearcuate grooves it until they reach the upper ends of the arcuateportions of those grooves.

At this time the sections 6 and 1 will be in parallel positions, edge toedge, as shown in Fig. 2, and with the rollers 9 at the top of thegrooves 10. A slight forward movement of both sections will then carrythe rollers 9 down the inclined. grooves ll into the positions shown inFig. 2. Both links l6 and 22 are then forwardly and upwardly inclined,so that any rearward push on the front section 6 will cause the sections6 and I to rise on the links 16 and 22 and the rollers 9 to ride up onthe cam grooves ll Thus, ordinary forces acting against the sections 6and 'l will not move them out of the horizontal position shown in Fig.2, or cause the sections to fold book-like into the closed positionshown in Fig. 1. The engagement of the rollers 9 in the forward ends ofthe grooves ll, limits the forward movement of the sections 6 and I. Theengagement of the rollers 9 with the bottoms of the grooves I and theengagement of the links 16 against the cross member 4 serve to hold thefolded sections and l in their upstanding, rearwardly inclined positionsshown in Fig. l. The adjacent abutting edges of the sections 8 and I areopen, except for short upstanding flanges 24 and 25 in sections 6 and 1respectively that serve as stops to limit endwise movements of mattresssections 26 and 21 disposed in sections 6 and I respectively. Eachmattress section has a small notch in the end engaging with the stop 24or 25, so that that mattress sections will abut edge to edge when thesections are open fiat as shown in Fig. 2. The mattress sections will beheld against downward sliding movement by the stops 24 and 25, see Fig.1, when the sections are together, face to face.

It will be noted that when the sections are opened out from the Fig. 1positions to the Fig. 2 positions, the links I6 move into forwardly andupwardly inclined positions, during which the pivots l5 move throughvertical dead center positions. A seat cushion 28 is removably'mountedon the cross members, 3 and 4 in front of the folded sections 6 and 1.Between the end walls l3 and 14 of section 6, an upholstered backing orcushion 29 is confined against the bottom wall l2, at the opposite facethereof from the mattress section 26. This cushion 29 serves as the backof the soft seat when the cushions 6 and l are upstanding, as in Fig. 1.

In the embodiment of the invention illustrated in Figs. 4 and 5, theconstruction is the same as explained in Figs. 1 to 3, except that thelinks 22 are eliminated, and in place thereof the inside faces of theend members I and 2 carry rollers 30 which engage against convex edgesor rails 3| provided on the end walls l9 and 20 of the rear section 1.These rollers 30 engage beneath the widest parts of the convex edges ofthe end walls l9 and 20 of the section 1, so that the sections 6 and Icannot sag when in upstanding positions. When the section 6 is pulledforwardly, the convex edges 3! will ride upon and along the rollers 30and fulcrum therein while moving backwardly and forwardly, until thesections assume the bed position shown in Fig. 5. The rollers 30 thussupport the rear section I in the horizontal position as well as in theupstanding position shown in Fig. l, and replace the links 22.

The links 22 and rollers 30 both function as fulcrums which support therear section 1 while it rocks and moves backwardly and forwardly.Otherwise, the construction and operation of the 4 structure of Figs. 3and 4 are the same as described for Figs. 1 to 3, and correspondingparts have corresponding numerals applied thereto. The upper surface ofthe seat cushion 28 is at the usual or any desired level for sofa seats,and the upper surfaces of the mattress sections 26 and 21 are at thedesired or usual mattress level for beds. It will be noted that nomechanical locks are required to hold the parts in either the sofa seatpositions or the bed positions, and the moving parts are sufficientlycounterbalanced so that relatively small forces are sufficient toconvert the device from a sofa seat condition to bed condition, and viceversa.

It will be observed that engagement of rollers 9 in the grooves ID willguide the frame sections in their opening and closing movements, in thesame manner whether the rollers are entirely on the section 6 or section1, or at their junction. The cam grooves H] will, of course, have shapesand positions depending upon where the rollers 9 are located on theframe sections.

It will be further observed that when the frame sections 6 and 1 areopened out into bed positions, shown in Figs. 2, 3 and 5, they aresupported at three positions from front to rear, which are on pivots l5,8 and 2| in Figs. 1 to 3, and on pivots l5 and S, and fulcrums 30, Figs.4 and 5. In all cases, one of these support points is always lockedagainst accidental closing of the sections. The weight of the sectionson links [6 and 22 will resist closing, as also the rollers 9 must rideup an inclined portion ll of the groove Ill before the sections mayclose. In the embodiment of the invention shown in Figs. 4 and 5, theweight of forward section 5, when the frame is opened into a bed, isapplied to link 16 in a direction to keep the sections opened, androller 9 in the inclined groove section II also resists closing of thesections. In both embodiments there is always at least one locking ofthe sections 6 and 1 against closing, and hence no manually operatedlatches are necessary to keep the frame sections in their open or bedpositions or whichmust be operated when the device is converted into abed or back into a sofa seat. The cam grooves l0 may be curved or shapedto carry the links l6 through vertical dead center positions during anypart of the opening movements, if one so desires.

It will be understood that various changes in the details andarrangements of parts which have been herein described and illustratedin order to explain the nature of the invention, may be made by thoseskilled in the art within the principle and scope of the invention asexpressed in the appended claims.
